Low-voltage electrical apparatus manufactures field.
Background technology
Drawer-type intelligent omnipotent breaker body is movably mounted on drawout chassis, and breaker body with take out
Have in relative separation, test, connection procedure between drawer seat and separate, test, connecting three stable job site situations.It is disconnected
At the separation point position completely disengaged from main circuit, it can be unloaded road device body from drawout chassis, it is also possible to be moved forward to
Testing position；Breaker body is not exclusively connected in testing position with main circuit, and to safeguard as detection necessary safety is provided
Environment, in testing position, breaker body can move forward to link position, can also move backwards to separation point position.
Breaker body is fully connected in link position with main circuit, chopper completely into normal working condition, in connection position
Put, breaker body can move backwards to testing position.As modernization intelligence is for the fast development of distribution technique, to intelligence
The requirement more and more higher of type omnipotent breaker, in particular for the relative connection provided between breaker body and drawout chassis,
Test, separate three positions chopper location status, and can correspondingly connection, test, separation point position output be corresponding electrically
Control and instruction switching signal, can meet the requirement of local maintenance maintenance, and intelligent supply and distribution network can be realized to intelligence
Change online transfer and remote monitoring that the location status of universal circuit breaker accurately show.However, existing universal circuit breaker is usual
The function that connection, test, detached three location status are indicated is realized using purely mechanic instruction structure, although can meet local
The needs of Maintenance and Repair, but can not will connection, test, detached three location status be converted to can be used for remote monitoring instruction
Output switch parameter mode, therefore intelligent supply and distribution network can not be met to the whole condition monitoring of intelligent universal circuit breaker
Need so as to which application is restricted.
Using microswitch by connect, test, separation point position be converted to can be used for remote monitoring instruction switching signal or
The way of output of on/off control is relatively passed through current, such as Chinese invention patent application of Publication No. CN 102290725,
Disclose a kind of three-position switching value output technology for drawer type frame breaker, it using the original planker of open frame circuit breaker with
The mode that contact switch is directly touched, realizes the conversion and output of three position switch amount.But due to planker rectilinear movement
Rectilinearity precision is very low, so making planker randomly generate the substantial amounts of excess of stroke when coordinating with contact switch touching, that is to say, that
Planker is actual to touch the change in location for coordinating with contact switch greatly, and contact indicates that switch over travel is less and more fine, takes out
The transmission impulsive force of drawer seat is larger, it is clear that this excess of stroke or shift in position are greatly destroyed for contact switch is easily caused, then
More heavy plus universal circuit breaker body, it generally adopts screw drive, planker to be directly driven by screw rod, needs big drive
Power, makes planker not only have very big dynamics for the active force of contact switch, but also with very strong rigidity, and guide rail
Straight-line guidance precision it is again very low, it is difficult to the impulsive force and stroke accuracy of the breaker body in motion are controlled by.Then,
So big destructive power and active force directly acts on the contact switch of fine switch over travel very little, for making for contact switch
The threat degree constituted with the life-span is obvious.For another example No. 202839489 Chinese utility model patents of CN, it is open
Three position of a kind of chopper five state output device of the electrical signal, due to rotating shaft for the active force of microswitch not only has very
Big dynamics, but also with very strong rigidity, thus the patent structure service life of microswitch is also constituted it is very big
Threaten.If controlling using the straight-line guidance precision of raising guide rail, reduction driving force and impulsive force or directly breaker body
The technological means of stroke accuracy can solve the above problems, but thus manufacture difficulty, assembling cumulative errors, production caused by institute
The multiple deterioration of cost and performance so that these technological means lack Practical significance.

As shown in Fig. 1 a kind of open frame circuit breaker with position instruction of the invention, including by supporting Guiding machine
Structure 4 is removably and the ground that can move linearly supports the Body switch 3 on drawout chassis 2, its moving direction y and supporting side
It is mutually perpendicular to (referring to Fig. 2) to z, described Body switch 3 is movable under the driving of handle screw component and stops respectively
Relative separation, test between drawout chassis 2, it is connected on three operating positions.With reference to shown in Fig. 1-3, wherein described is disconnected
Road device also includes position instruction component 1 and the instruction actuator 100 being fixedly mounted on the little side plate 31 of Body switch 3, is used for
Body switch 3 be moved respectively to the relative separation between drawout chassis 2, test, be connected three operating positions when, by one by one
With the percussion cooperation for separating lever 15, testing lever 16, connection lever 17, separation lever 15 is ordered about respectively and contact switch is separated
12 touchings coordinate, testing lever 16 coordinates with the touching of test contact switch 13, be connected lever 17 touches with connecting terminal switch 14
Coordinate.Described position instruction component 1 includes the fixed plate 11 being fixed on the big side plate 21 of drawout chassis 2 and is fixed on described solid
In fixed board 11 separation contact switch 12, test contact switch 13, connecting terminal switch the 14, first location axle pin 12C, second determine
Position pivot pin 13C and the 3rd location axle pin 14C, and in the mode of being rotatably assorted be arranged on the first location axle pin 12C, second determine respectively
Separation lever 15, testing lever 16 and connection lever 17 on position pivot pin 13C and the 3rd location axle pin 14C, described first is fixed
Position pivot pin 12C, the second location axle pin 13C and the 3rd location axle pin 14C axis direction x it is identical, the first location axle pin 12C, the
The axis direction x of two location axle pins 13C and the 3rd location axle pin 14C is vertical with the moving direction y of Body switch 3, and it
The axis direction x it is vertical with supporting direction z of Body switch 3.
The open frame circuit breaker with position instruction of the present invention includes drawout chassis 2, the and of Body switch 3 of known structure pattern
Handle screw component, drawout chassis 2 has the big side plate 21 of fixed bearing guiding mechanism 4；Body switch 3 is by supporting guiding mechanism
4 removably support on drawout chassis 2, and Body switch 3 is movable to simultaneously under the driving of handle screw component
Rest on separation, test, connect on three operating positions.Supporting the function of guiding mechanism 4 is：For Body switch 3 removably
It is installed on drawout chassis 2 and stable support is provided；Can move to for Body switch 3 and rest between drawout chassis 2 relative separation,
Test, connection provide mobile guide on three operating positions.Therefore, referring to Fig. 2, carried from supporting guiding mechanism 4 to Body switch 3
For supporting certainly exist supporting direction z, supporting direction z is relevant with gravity, and in other words supporting direction z is vertical
's.The mobile guide provided to Body switch 3 from supporting guiding mechanism 4, it necessarily causes Body switch 3 to have moving direction y,
In order that Body switch 3 can stably rest on above-mentioned separation, test, connect on three operating positions, then require that body is opened
The moving direction y for closing 3 is horizontal direction, in other words, it is desirable to which the moving direction y of Body switch 3 and supporting direction z are mutually perpendicular to.
With reference to Fig. 1 it is conceivable that, supporting guiding mechanism 4 has for the straight-line guidance precision for moving in the y-direction that Body switch 3 is provided
Following characteristics：Straight-line guidance error very little in a z-direction, straight-line guidance error in the x direction is larger, in other words, this
Body switch 3 during moving in the y-direction occur the random offset very littles to z directions, and to x directions random offset compared with
Greatly.The function of the position indicator of the present invention is exactly to indicate that Body switch 3 (refers to relative to three operating positions of drawout chassis 2
Separation point position, testing position and link position).At separation point position, it is completely disengaged from Body switch 3 with main circuit, in this point
Off normal and put, Body switch 3 can be unloaded from drawout chassis 2, it is also possible to be moved forward under the driving of handle screw component
Testing position；In testing position, it is not exclusively connected Body switch 3 with main circuit, and to safeguard as detection necessary peace is provided
Full environment, in this testing position, by the driving of handle screw component, can make Body switch 3 move backwards to separation position
Put, can also move forward to link position；In link position, it is fully connected Body switch 3 with main circuit, so that universal
Chopper on this link position, by the driving of handle screw component, opens can body completely into normal working condition
Close 3 and move backwards to testing position.Handle screw component has following functions：The artificial operation for rotating handle, just can order about this
Body switch 3 moves linearly；Stop handle rotating, Body switch 3 just can be made slack.Described handle screw component can be adopted
Known structure realizes that the structure is such as：One screw mandrel only with a rotational freedom is set on drawout chassis 2 (in figure not
Illustrate), the diameter parallel of screw mandrel is fixedly installed one in Body switch 3 and matches somebody with somebody with screw mandrel in the moving direction y of Body switch 3
The nut (not shown) of conjunction, nut can not be rotated, and when handle drives screw mandrel is rotated, nut drives under the driving of screw mandrel
The moving direction y movements that Body switch 3 is limited along supporting guiding mechanism 4.The structural advantages of this handle screw component are, it
With the auto-lock function to Body switch 3, i.e., in the state of Body switch 3 rests on separation, test or link position, as long as
The auto-lock function of not rotary screw rod, screw mandrel and nut is restricted can the movement of Body switch 3.Because handle screw component can
To provide very big driving force to Body switch 3, and driving force has very strong rigidity, and passes through turning for handle drives screw mandrel
Dynamic smooth performance and precision characteristic extreme difference again, so that the stop of Body switch 3 has two large problems, one is stop place
Repeatable accuracy is extremely low, the excess of stroke is big (exists between i.e. actual stop place and preferable operating position very big advanced or stagnant
Afterwards), two is in the moment for stopping Body switch 3 to be made to discharge very big impulsive force.Thus it is conceivable that, if using existing
Body switch and contact switch directly touch the scheme of cooperation, then the destruction that finer contact switch is subjected to is very tight
Weight.
It should be appreciated that arriving, for this guide rail, to avoid above-mentioned destruction, routinely want improve its rectilinear movement precision and
The design of the repetitive positioning accuracy in space is extremely difficult and expensive, but only obtains the essence of the resetting in its supporting direction z
Degree is relatively much easier, much low, and the construction of the present invention is also based on this principle to design, specifically, this
The construction of invention is not to open from the rectilinear movement precision (usually said is directly or not mobile) and body of control Body switch 3
The repetitive positioning accuracy for closing 3 space sets out, but make use of the construction featuress and Body switch 3 of supporting guiding mechanism 4 compared with
The repetitive positioning accuracy in supporting direction z that the characteristics of by heaviness is formed, therefore realize and with low cost with easy
Effect.The embodiment for supporting guiding mechanism 4 of the invention be given using such as Fig. 2 and its advantage of replacement scheme are：It is readily susceptible to
The detachable supporting for realizing Body switch 3 installs, is readily susceptible to obtain resetting essence of the Body switch 3 in supporting direction z
Degree.The concrete structure of the supporting guiding mechanism 4 of the present invention can have kinds of schemes, and one kind is preferably scheme as depicted in figs. 1 and 2：
Described supporting guiding mechanism 4 includes the load-carrying guide rail 41 being fixed on the big side plate 21 of drawout chassis 2, is fixed on Body switch 3
Little side plate 31 on load-bearing axle 42 and the rolling member 43 that is sleeved in load-bearing axle 42, the axis direction of load-bearing axle 42 respectively with this
The moving direction y of body switch 3 is vertical with supporting direction z, and rolling member 43 is oriented to the supporting of load-carrying guide rail 41 and coordinates.It is another alternative
Scheme can be：Described supporting guiding mechanism 4 includes the load-bearing axle being fixed on the big side plate 21 of drawout chassis 2, is fixed on
Load-carrying guide rail on the little side plate 31 of Body switch 3 and the tumbler being sleeved in described load-bearing axle, the axis side of load-bearing axle
To vertical with the moving direction y of Body switch 3 and supporting direction z respectively, tumbler is oriented to load-carrying guide rail support and coordinates this
Hold cooperation.Obviously, the difference between the scheme and replacement scheme shown in Fig. 2 is：The installation of load-carrying guide rail 41 and load-bearing axle 42
Relation difference (installation relation is exchanged with each other)；Rolling member 43 is different from the motion mode of tumbler, i.e. the motion side of rolling member 43
Formula is to roll (rotate but also move) not only, and the motion mode of tumbler is only rotated (do not move).
Contrast aforesaid employing screw rod direct drive planker, planker directly to coordinate with contact switch touching, and contact is opened
The layout structure scheme of the prior art that the relation that is fixedly connected is set up with the base plate front of drawout chassis is closed, the big of planker is not only caused
Driving force and impulsive force directly act on contact switch, and each action piece relevant with position instruction and its their action are equal
Launch in the horizontal plane, and the rectilinear movement precision of planker provided by guide rail is difficult to improve, particularly in the horizontal direction
Steering error is bigger, the collective effect of the excess of stroke error of the error and planker, result in planker resetting in the horizontal plane
Error is big, and planker and the extreme position that contact switch is touched be (extreme value of the minimum distance between corresponding planker and contact switch
Planker position) accuracy and stability can not possibly improve because being affected by resetting error, therefore planker can not be relaxed
The excess of stroke area requirement.Additionally, resetting error can also affect the reliability that cooperation is touched between planker and contact switch.
And the present invention is as a result of position instruction component 1, instruction actuator 100 and is fixedly mounted on outside the big side plate 21 of drawout chassis 2
The organization plan of the fixed plate 11 in face, the large driving force and impulsive force that not only avoid Body switch 3 directly acts on contact and opens
Close, and position instruction component 1 each action piece and its their action launch on vertical guide, and position instruction component
1 additionally uses each location axle pin 12C, 13C and the axis direction x of 14C and the moving direction y of Body switch 3 and supporting direction z hangs down
Straight layout structure so that the steering error in the x directions in the horizontal plane of supporting guiding mechanism 4 does not affect to indicate actuator 100
Percussion with each lever 15,16 or 17 coordinates, and supports the high accuracy of the resetting in supporting direction z of guiding mechanism 4 so that thick stick
(lever positions of the extreme value of the minimum distance between correspondence lever and contact switch, should for the extreme position that bar 15,16 or 17 swings
Position is corresponding with the position for indicating actuator 100) there is higher accuracy and stability.That is, tube body is not opened
Close 3 the excess of stroke it is much, the actual swing position of lever 15,16 or 17 is all without surmounting described extreme position, therefore the excess of stroke is missed
Difference will not also constitute the threat of destruction contact switch, not affecting lever 15,16 or 17 and contact switch 12, between 13 or 14
Touching coordinate reliability on the premise of, can suitably relax the requirement of the excess of stroke error of Body switch 3, with reduce manufacture difficulty and
Production cost.
The position instruction component 1 of the open frame circuit breaker of the present invention includes being fixed on the outside of big side plate 21 of drawout chassis 2
Fixed plate 11, separation contact switch 12, test contact switch 13, connecting terminal the 14, first location axle pin 12C of switch, second are determined
Position pivot pin 13C and the 3rd location axle pin 14C, and in the mode of being rotatably assorted be arranged on the first location axle pin 12C, second determine respectively
Separation lever 15, testing lever 16 and connection lever 17 on position pivot pin 13C and the 3rd location axle pin 14C is arranged at this and fixes
On plate 11.Fixed plate 11 is fixed on the fixed connection structure of the outside of big side plate 21 of drawout chassis 2 can various ways, such as Fig. 1 institutes
Being fixedly connected for the employing screw 10 for showing, is not excluded for being fixedly connected using alternate manner certainly.Separate contact switch 12, test
The fixed connection structure that contact switch 13, connecting terminal switch 14 is respectively and fixedly installed in fixed plate 11 can have various ways,
Generally adopt general screw attachment structure.The priority of Body switch 3 move to the relative separation of drawout chassis 2, test, be connected
During three operating positions, indicate that the priority of actuator 100 is tapped and coordinated with lever 15, testing lever 16 and connection lever 17 is separated,
Percussion cooperation orders about respectively separation lever 15 and separates the touching cooperation of contact switch 12, testing lever 16 and test contact switch
13 touchings coordinate, connection lever 17 coordinates with the touching of connecting terminal switch 14.Here so-called percussion cooperation refers to instruction actuator
100 contact and extrude separation lever 15, testing lever 16 or connect the cooperation of lever 17, certainly, leave in instruction actuator 100
In the case of separating lever 15, testing lever 16 or connection lever 17, described percussion cooperation is released from.Here so-called touching is matched somebody with somebody
Conjunction refers to that separation lever 15 contacts and make to separate the permutator state of contact switch 12, testing lever 16 with contact switch 12 is separated
Contact and make test contact to switch 13 permutator states, be connected lever 17 with connecting terminal switch 14 with test contact switch 13
Contact and make connecting terminal switch 14 permutator states cooperation, certainly, indicate actuator 100 leave separation lever 15,
In the case of testing lever 16 or connection lever 17, separate lever 15 and separate the answering in separation contact switch 12 of contact switch 12
On off state is automatically reset and recovered under the power effect of position, and testing lever 16 and test contact switch 13 are in test contact switch 13
On off state is automatically reset and recovered under reset force effect, and connection lever 17 and connecting terminal switch 14 switch 14 in connecting terminal
Reset force effect under automatically reset and recover on off state.Obviously, after using position instruction component 1 and instruction actuator 100,
Body switch 3 can be completely avoided directly to coordinate with separating contact switch 12, test contact switch 13, connecting terminal switch 14 and touching
Impulse transfer problem so that the large driving force and impulsive force of Body switch 3 can not directly act on each contact switch.The present invention
Using the axis direction x of the first location axle pin 12C, the axis direction x of the second location axle pin 13C and the 3rd location axle pin 14C
